MX-4101N  FIRMWARE UPDATE  9 – 2

The firmware update executes by SIM49-01.

Insert the media or USB memory which stores the firmware
into the main unit.

The screen transfers to the update screen.

* The number of key changes according to the number of the

sfu file in the media or USB memory inserted.

* If the media or USB memory was not inserted when entry to

the SIM49-01 screen, "INSERT A STORAGE FIRMWARE
STORED ON [OK]" is displayed on the screen. Insert the
media or USB memory and push the [OK] key to open the
file. If the media have not been inserted and [OK] key is
pushed, the next screen does not appear and the screen
waits the entry. Conversely, if the media or USB memory is
pulled out on the file list screen, the error is detected by the

If firmware's key is not selected, [EXECUTE] is gray out and
cannot be pressed.

* Press the selected key again to release the selection.
* Press [ALL] key to select all items.

5)

Press [EXECUTE] key. “ARE YOU SURE? [YES] [NO]”
becomes clear. Press [YES] to start the update of selected
firemware.

The progress is displayed on right side of "FIRMWARE
UPDATE" title by 20 steps.

At this time, only the progress gauge is displayed on the
screen, and the version and the firmware selection key are not
displayed.

6)

If the update is normal completion, following screen is dis-
played.

Exit the simulation mode and turn off the power.
Go to Simulation 22-05 and confirm the firmware has
upgraded successfully.

7)

If the update is not normal completion, following screen is dis-
played.

* When the power supply is turned off due to a black out etc. while

updating or when the update terminated abnormally, a part of the
main program stored in HDD may be damaged and may not
booted normally.
In this case, the emergency update described later must be exe-
cuted.
